Im new to this so all please bare with me probably a dumb question but i have no clue. Ok so for 4wd when do i use 4hi and when do i use 4lo. Whats the difference?
I'm assuming its the same pattern as my TJ. If so its one pull up to go into 4hi, then you move the lever to the right to clear the "nib" or whatever, once it clears the nib you're in neutral I'm pretty sure. from there one pull up is 4lo. There should be a visual on your shifter.NFRs2000NYC said:
Damn good explanation! Only difference with JK's I believe you can be traveling 3-5mph when shifting in to 4 lo. No reason to though, especially if you arent experienced. If you need a little more speed in 4lo its fine to be in 2nd or 3rd gear also. On rough trails I usually run 4lo 2nd gear unless actively climbing/crawling steep hills up or down.You use 4hi when you're on a slick surface and need more traction (ex. Enough snow that you can't see pavement, wet grass, mud, slick rock, etc). 4hi has a 1:1 ratio, this means that the input from the transmission and output from the transfer case (your driveshafts) spin at the same speed. 4lo uses gear reduction to reduce the speed of the output shaft to either 2.73:1 if you have a Wrangler X, Sport, or Sahara, and 4:1 if you have a Rubicon. What this reduced speed does is multiply torque, allow increased control by being able to move slower, and the slower speed reduces the chance of tire slippage. Use 4lo when you need very precise movements or need to move very slow off road on technical trails or when crawling on some rocks or even crossing water. I can't think of a single situation besides perhaps pulling someone out of a ditch when you would need 4lo on road. Also I should mention that when shifting into 4lo you must either be still or rolling 1-3mph, disconnect power to the transfercase by placing the transmission in neutral or clutching in,then pull from 4hi through N to 4lo. This is just a quick over view but I hope it helps!
It should say "N" right there on the shifter at the position that neutral is.... I know mine did.
